CROSS-REFERENCE TO RELATED APPLICATIONS

This application is a continuation of U.S. application Ser. No. 13/652,337, filed on Oct. 15, 2012, which is incorporated by reference herein in its entirety.

BACKGROUND

Users may be inundated with massive amounts of data making it difficult to manage and harness the data effectively. Users can easily suffer from information overload. Data formatted in grids or other arrangements may be unmanageable, making the data ineffective for the user. Tools and functions have been developed to allow users to manipulate the presentation and display of the data to better understand the data. Filtering data is one such important function, helping users focus attention on data that fits the particular criteria of the filter. Typically a user selects a menu option to apply filtering. A filter dialog box then appears and the user inputs the right spelling or capitalization to accurately filter the data. This conventional filtering process is time consuming and susceptible to user input errors, especially for users that filter data repeatedly.

SUMMARY

Embodiments of a system are described. In one embodiment, a data filtering system includes a display device and a data filtering engine coupled to the display device.

DETAILED DESCRIPTION

It will be readily understood that the components of the embodiments as generally described herein and illustrated in the appended figures could be arranged and designed in a wide variety of different configurations. Thus, the following more detailed description of various embodiments, as represented in the figures, is not intended to limit the scope of the present disclosure, but is merely representative of various embodiments. While the various aspects of the embodiments are presented in drawings, the drawings are not necessarily drawn to scale unless specifically indicated.

The present invention may be embodied in other specific forms without departing from its spirit or essential characteristics. The described embodiments are to be considered in all respects only as illustrative and not restrictive. The scope of the invention is, therefore, indicated by the appended claims rather than by this detailed description. All changes which come within the meaning and range of equivalency of the claims are to be embraced within their scope.

Reference throughout this specification to features, advantages, or similar language does not imply that all of the features and advantages that may be realized with the present invention should be or are in any single embodiment of the invention. Rather, language referring to the features and advantages is understood to mean that a specific feature, advantage, or characteristic described in connection with an embodiment is included in at least one embodiment of the present invention. Thus, discussions of the features and advantages, and similar language, throughout this specification may, but do not necessarily, refer to the same embodiment.

Furthermore, the described features, advantages, and characteristics of the invention may be combined in any suitable manner in one or more embodiments. One skilled in the relevant art will recognize, in light of the description herein, that the invention can be practiced without one or more of the specific features or advantages of a particular embodiment. In other instances, additional features and advantages may be recognized in certain embodiments that may not be present in all embodiments of the invention.

Reference throughout this specification to “one embodiment,” “an embodiment,” or similar language means that a particular feature, structure, or characteristic described in connection with the indicated embodiment is included in at least one embodiment of the present invention. Thus, the phrases “in one embodiment,” “in an embodiment,” and similar language throughout this specification may, but do not necessarily, all refer to the same embodiment.

While many embodiments are described herein, at least some of the described embodiments facilitate filtering data quickly and efficiently. In many instances, it is difficult to efficiently and accurately filter data. Tables and spreadsheets today may contain tens of thousands of cells or more. Filters allow users to understand, interpret, and analyze subsets of data within a table or spreadsheet by locating or displaying only the data that satisfies the filter.

Applying a conventional filter typically involves a user selecting a filter option on the menu of an application. Upon selection, a dialog box prompts the user to input the desired filter language. For users continually applying filters, this process can be time consuming and frustrating. In addition, the user typically manually inputs the correct filter language or criteria. The user needs to be familiar with the correct spelling and capitalization to correctly apply the filter. The user may just enter a typo. Incorrect capitalization or a misspelled word leads to user frustration and inefficiency or worse. A user unaware of a misspelled filter may reach incorrect conclusions based on an incorrect filtered data set.

Some embodiments described herein allow the user to apply a filter based on a cell value or cell entry without typing anything by selecting the filter icon within the cell. There is no opportunity to misspell the filter language. Some embodiments significantly reduce the time to apply a filter by applying after a single mouse-click or other user input. Accurate and quick application of filters reduces user frustration and increases user satisfaction. Users who apply filters continually do so quickly and efficiently.

FIG. 2A depicts one embodiment of a data set 200 configured in rows 202-210 and columns 212-220 with a filter icon 224 displayed within a cell 226. In some embodiments, the data set 200 is displayed on the user interface 116 of the display device 114. In this embodiment, the first row 202 of the data set 200 contains column headings. In this embodiment, the remaining rows 204-210 are groups of related data, known as a record, tuple or other set of related data. The rows 204-210 contain data that may be filtered. In this embodiment, the data set 200 is sales information. The data in each row 204-210 relate to sales transactions, with each attribute of the transaction aligned under columns 212-220. In this embodiment, the columns 212-220 are cell sets 212-220. The sales information includes the location of a sale, the sales unit involved, the date of the sale, the revenue generated, and the number of salesmen involved in the sale. For simplicity, a small data set 200 is shown in FIGS. 2A-2F. In this embodiment, the filter functionally allows a user to view only the sales information of a single region (e.g. East or West), a single sales unit (e.g. 1, 2, or 3), or a single date (e.g. 9/17 or 9/18), etc. A filter allows the user to focus attention on a subset of data while ignoring the rest. FIG. 2A also depicts a cursor 222 located in a cell 226 and a filter icon 224 located at a left perimeter of the cell 226. The cell 226 contains a cell entry 228 of “9/18.” Although the filter icon 224 is shown with a specific graphical depiction—a block letter F—other embodiments may utilize other graphical or visual elements to represent the filter icon 224 in the cell 226. In other embodiments, the filter icon 224 may be located anywhere in the cell 226 or only partially in the cell 226.

FIG. 2B depicts the data set 200 of FIG. 2A with the cursor 222 moved and the filter icon 224 displayed in a different cell 230. In this embodiment, the user has moved the cursor 222 to a new cell 230, and the filter icon 224 disappears from the cell 226 and displays in the cell 230. In some embodiments, the filter icon 224 appears when the cursor 222 hovers over the cell 230 for a period of time. In some embodiments, the filter icon 222 will disappear from the cell 226 when the cursor 222 leaves the cell 226, appearing in the cell 230 where the cursor 222 relocates. In some embodiments, the filter icon 224 is displayed in all cells of the data set 200 regardless of the location of the cursor 222. In some embodiments, the filter icon 222 is displayed only in cells containing a cell entry 228. Some embodiments do not include a cursor 222.

FIG. 2C depicts the data set 200 of FIGS. 2A and 2B with the data set 200 filtered according to the cell entry 228. The data set 200 has been filtered upon selection of the filter icon 224. In this embodiment, the cell set 216 is filtered for data equaling the cell entry 228. Cells 226 and 230 are displayed along with the related data in rows 206 and 208.

The filter icon 224 is displayed in cell 234 and the cell entry 232 is displayed as a hyperlink. In some embodiments, the cell entry 232 is metadata. In some embodiments, when the cell entry 232 is metadata, the cell entry 232 is displayed as a hyperlink. The hyperlink links to the data associated with the metadata. In some embodiments, the cell entry 232 displays as a hyperlink after the cursor 222 hovers over the cell 234 for a period of time. In some embodiments, each cell entry 232 that supports linking to further data is displayed as a hyperlink regardless of the location of the cursor 222. Some embodiments do not include the cursor 222.

FIG. 2E depicts the data set 200 of FIG. 2D and the metadata 236 associated with the cell entry 232. In this embodiment, the metadata 236 is displayed below the cell 234. In some embodiments, the metadata 236 is a separate database, table, spreadsheet, or other collection of data located in a distinct file. In some embodiments, the metadata 236 is a separate sheet, database, or table located in the same file. In some embodiments, the metadata 236 resides in a different application. In this embodiment, the metadata 236 associated with the cell entry 232 (i.e. “2”) are the names of the two salesmen responsible for the sale (i.e. “Roger” and “Jackie”). In some embodiments, the metadata 236 is displayed in different ways. The metadata 236 may be displayed in a different location within data set 200 or may be displayed as a pop-up window. The metadata 236 may be displayed within the same cell as the original cell entry 232 in which the metadata 236 is associated or may be displayed in an entirely different format. In this embodiment, the cell entries 238 and 240 are also displayed as hyperlinks. The cell entries 238 and 240 link to further data detailing each cell entry, respectively. In some embodiments, the user may drill down on multiple levels of data quickly and efficiently with a single click of a hyperlink.

FIG. 2F depicts the data set 200 of FIG. 2A and a filter dialog 242 containing an entry field 244 automatically populated with the cell entry 228. In this embodiment, the filter dialog 242 is displayed in response to the selection of the filter icon 224. In this embodiment, the filter dialog entry field 244 is automatically populated with the cell entry 228. In some embodiments, the filter dialog 242 is configured to filter for values equal to the cell entry 228. In other embodiments, the filter dialog 242 is configured to filter for values less than or more than the value of the cell entry 228. In some embodiments, the filter dialog 242 is configured to filter for values that begin with the cell entry 228 and so on. In some embodiments, the filter dialog 242 includes an execute button 246 that when selected applies the filter. In some embodiments, the user may change or alter the automatically populated value of the entry field 244. In some embodiments, the filter dialog 242 includes additional entry fields 248 enabling application of additional filters. In some embodiments, the additional entry filed 248 is automatically populated according to other cell entries 228 of the data set 200 or cell set 216. In some embodiments, the filter dialog 242 is displayed in a separate window, in a pop-up, in a ribbon of an application, in a menu, or otherwise similarly displayed.

In addition to the advantages which may be achieved by implementation of the individual components of the data filtering system 100, some embodiments of the data filtering system 100 provide additional advantages over conventional technology. For example, some embodiments of the data filtering system 100 allow a user to quickly apply a filter with a single mouse click. Some embodiments reduce or eliminate the possibility of an error in spelling or capitalization by basing the filter on the cell entry. In some embodiments, filters are applied without typing a single keystroke.

FIG. 3 depicts a flow chart diagram of one embodiment of a method for data filtering 300. Although the method for data filtering 300 is described in conjunction with the data filtering system 100 of FIG. 1 and the data set 200 of FIGS. 2A-2F, embodiments of the method for data filtering 300 may be implemented with other types of computer systems.

At 302, a cell set 216 is displayed on a display device 114. The cell set 216 contains data of a common data type and at least one cell 226 contains a cell entry 228. At 304, a filter icon 224 is displayed within at least one of the cells 226 of the cell set 216. At 306, a filter is applied to the cell set 216 in response to selection of the filter icon 224. The depicted method for data filtering 300 then ends.

In some embodiments, the filter is based on the cell entry 228. Some embodiments include distinguishing filtered data 206-208 that fulfills a logical rule relating the filtered data 206-208 and the cell entry 228 from sifted data 204 & 210 that does not fulfill the logical rule relating the sifted data 204 & 210 and the cell entry 228. Distinguishing may include exclusively displaying, moving, or otherwise visually emphasizing the filtered data 206-208. In some embodiments, only the cell set 216 is displayed. In other embodiments, the data set 200 is displayed showing the related data of cell sets 212-214 and 218-220. In some embodiments, the data set 200 is filtered for the exact value of the cell entry 228. In some embodiments, the data set 200 is filtered for values greater than or less than the value of the cell entry 228. In some embodiments, the data set 200 is filtered for a range of values above and/or below the value of the cell entry 228. In some embodiments, the data set 200 is filtered for similar values as the cell entry 228 or values that begin with the cell entry 228. In some embodiments, only the cell set 216 is filtered.

In some embodiments, the method for data filtering 300 further includes displaying a filter dialog 242 in response to the selection of the filter icon 224 by the user. In some embodiments, the filter dialog entry field 244 is automatically populated with the cell entry 228. The filter may be configured to filter according to many different criteria. The criteria may include but is not limited to filtering for values equal to, greater than, less than, begins with and so on. In some embodiments, the filter dialog 242 includes additional entry fields 248 that allow additional filters to be applied to the data set 200.

In some embodiments, the method for data filtering 300 includes applying additional filters to the data set 200 by selecting a second filter icon 224 displayed within at least a second cell 232 of a second cell set 220. The additional filters may be associated with each other using logical operations well known in the art including but limited to and, or, not, nor, equals, less than, greater than, and so on.

In some embodiments, the selection of the filter icon 224 is in response to a single user input. The input may be a single mouse click, a right-click, a left-click, a tap or other recognized touch gesture on a touch screen, a keystroke, a keyboard input, or another analogous single input. Some embodiments described herein increase efficiency by decreasing the time and/or the number of inputs required to apply a filter. In some embodiments, a single click of the filter icon 224 will apply a filter based on the cell entry 228.

In some embodiments, the filter icon 224 will appear within at least one cell 226 of the cell set 216 when the cursor 222 or an analogous pointer hovers over the cell 226 for a period of time. In some embodiments, the filter icon 224 is displayed in all cells 226 of the cell set 216 or the data set 200. In some embodiments, the filter icon 224 is displayed only in cells 226 that contain a cell entry 228.

Some embodiments of the method for data filtering 300 further include displaying a data set 200 including a plurality of cell sets 212-220. In some embodiments, the method for data filtering 300 includes applying at least one additional filter in response to a user input, the user input being selection of a second filter icon 224 displayed within at least a second cell 232 of a second cell set 220.

In some embodiments, the method for data filtering 300 further includes displaying the cell entry 234 as a hyperlink. In some embodiments, the hyperlink links to metadata 236 associated with the cell entry 234. In some embodiments, the metadata 236 is displayed in response to selection of the hyperlink. The metadata 236 may be displayed within the data set 200, within the cell set 220, as a pop-up box, in a separate file, in a separate window, or in another way. In some embodiments, the hyperlink is displayed when the cursor 222 or similar pointer hovers over the cell 232 for a period of time. In other embodiments, all cell entries 234 that link to metadata 236 are shown as hyperlinks.
